We are a couple around our 50ies and stayed at Kevin's hostel four nights after having stayed in Sultanahmet with the family for another couple of days. First thing we realised about the location, Kadiköy was that it's about half of the price level compared with the historic old town. Kevin's hostel is exceptionally well located in easy walking distance towards the ferry, busses, trams and train as well as to supermarkets, liquor shops, kebab eateries and the beautiful market area (east of Kadiköy's main road), not only markets but tea/ coffee rooms, all sorts of restaurants and beer bars, genius and way more genuine than we saw elsewhere.
We had a very good balcony room with a wonderful comfortable, big double bed, wardrobe, table & two chairs that we moved to the balcony to enjoy the quiet afternoons (the balconies go to the yard side, so a good night's sleep is guaranteed). There is a well equipped common kitchen and a huge bathroom was just across our room. EXCELLENT shower!!! The hostel has even a small backyard/ garden with common area to sit and talk, bbq facilities abundant.
The staff was very friendly and always ready to help and they were cleaning the house once a day, the bathrooms several times per day.
When back in Istanbul we are definitely coming back to stay here!
Thank you for everything!
